Purpose and characteristics 

The JTF-L10G Tower Crane Integrated Valve is a new product developed by our company, which has the characteristics of compact structure, high integration level, easy control and convenient installation. For the tower crane jacking cylinder, working pressure of its two chambers can be separately regulated; as a patented product in the jacking system of tower crane, it is applicable to the jacking system of tower crane and other hydraulic machinery with similar function.

Performance characteristics 

1. Since the oil inlet circuit is configured with a pilot-operated dynamic damping overflow valve, it is featured with good opening-closing property, strong anti-contamination ability and high reliability. The oil return circuit is configured with adjustable flow by-pass to control the return oil pressure, lower power consumption and reduce the system heating.

2. Both ends of the reversing valve hole are subject to structural design of zero leakage.

3. The pressure gauge port is reserved.
